    Lubrication, continued Oil Supply and Discharge Procedures Oil Supply Procedure • Always stop the unit before adding oil • Oil level may drop during operation, depending on the oil viscosity, temperature and direction of rotation. Additional oil is not necessary Check the oil level when the unit is stopped to ensure that it has the correct amount of oil • It may take some time for the oil to settle when the oil viscosity is high. Be careful not to add too much oil. • There may be two different oil fill locations for some combinations; refer to oil fill/ drain locations figure for details. • Consider implementing an oil analysis program to ensure lubricant continues to operate at peak performance. Follow your lubrication provider’s oil analysis recommendations to ensure reducer performance • Always consult factory and warehouses for overhaul of gearmotors and reducers. Familiarity with Cyclo products is necessary for proper overhaul 1. Remove the oil fill plug, as referenced in the Figures below.
